2.5 Temperature Sensor

Monitoring of the chip temperature is provided by the on-chip temperature sensor which delivers temperature-proportional voltage to the TEMP output. The temp. sensor can be independently biased through VCCTEMP.Thereby the chip temperature can be monitored while the main supply of the transceiver is switched off.

2.6 Power Detector

For RF output power indication, peak voltage detectors are connected to the output of the TX power amplifier andto the LO medium power amplifier. To eliminate temperature and supply voltage variations, a reference outputvoltage VREF is available through the ANA output for the TX and LO power sensor. The compensated detectoroutput voltage is given by the difference between VOUT and VREF for both power sensors respectively. This voltageis proportional to the RF voltage swing at the individual amplifier outputs, its characteristic is non-directional.

3.3 SPI1.) Three signals control the serial peripheral interface of the BGT24MTR11:SI (Data); CLK (Clock); CS (Chip select) 2.) The data bits SI (MSB first) are read in the shift register with falling edge of the CLK signal.Please make sure, that the data is present at least 10 ns before and at least 10 ns after the falling edge of theclock signal. 3.) The CLK and CS signals are combined internally.At least 20 ns before first rising edge of the first CLK signal CS needs to be in "low" state.While the Data is read, CS has to remain in "low" state.4.) When Data read in is finished, the shift register content will be written in the latch at the rising edge of the CSsignal. The time between the last falling edge of the CLK signal and the rising edge of the CS must be at least 20ns.
